While Sudusinghe faces deregistration as a doctor or suspension, his victim has suffered anxiety, paranoia, sleeping difficulties and a fear of and inability to trust doctors and people.

"And of course she's been put through the ordeal of giving evidence over two days this week," crown prosecutor Christopher Cook said.

Sudusinghe was acquitted of a rape charge but found guilty of the alternative, lesser sexual assault offence after the prosecution failed to prove there was penetration.

He was also found not guilty of attempted rape after it was claimed he tried to digitally penetrate the woman's vagina a second time, and of a sexual assault stemming from an allegation he slapped her on the buttocks.

Since being charged, Sudusinghe has been required to have a chaperone present while with female patients.

He went from seeing an average 60 patients per day to 15.

To one patient, he said: "God is punishing me for being naughty (to the victim)."

"She placed her trust in you to treat you in a professional manner," Judge Anthony Rafter SC said in sentencing.

"Your conduct involved a gross violation of the relationship between a doctor and patient.

"Further, she was accused by your counsel, no doubt based on instructions, that she was fabricating the allegations for financial gain.
